The Towers of Hanoi puzzle was published in 1883 by French mathematician Edouard Lucas, under the pen-name, N. Lucas de Siam.

The object of the game is to move all the disks onto a different pole. You can only move one disk at a time and you must follow size order -- a bigger disk can't go on a smaller disk. [Hint: try it with 3 disks to start with.]
